TRUE/FALSE: The parking brake system allows for gradual braking pressure to be applied.

• A. True
• B. Not applicable
• C. False
• D. Not determinable

Answer: (C)

The parking brake is designed to secure the aircraft when stationary, not to provide variable or gradual braking like the service brakes. When you engage it, the system applies a fixed brake force to lock the wheels (or rotor components) in place, and you don’t modulate that pressure gradually as you would with normal braking. For controlled deceleration or precise braking, you rely on the service braking system, which is hydraulically actuated and designed to vary pressure smoothly in response to inputs. So the statement about the parking brake allowing gradual braking pressure is false.
